Copy and reformat a codon usage table


codcopy reads and writes a codon usage table. Rather than a copy utility, it is intended as a format conversion utility so that codon usage data can be exported to other applications that support only a single format. This program supports all available codon usage input and output formats.



Here is a sample session with codcopy

% codcopy 
Copy and reformat a codon usage table
Codon usage file: Eecoli.cut
